For some travelers, the ultimate amenity is a ghost. In a recent survey, 44% of respondents said they had visited a haunted house. More than a quarter said they'd like to sleep in one. A good place to encounter a spirit might be a B&B, says Brian Megless of BedandBreakfast.com, survey sponsor. "The properties are unique and full of stories and historical importance," he adds. He shares some favorites with Larry Bleiberg for USA TODAY.

At the Black Horse Inn, three ghosts have been reported in this former Civil War hospital — a history that Megless notes "definitely makes it a little bit more creepy." One female spirit, believed to be a nurse, laughs in men's ears. Another spirit, the "Christmas ghost," seems to have toppled a Christmas tree several years in a row. Now the tree is wired to the wall. 540-349-4020; blackhorseinn.com
